The importance of securing correct diagnoses in the cases reported as 

 dying of infantile convulsions is at once evident in view of the fact that 

 35 per cent of the total mortality under 1 year is given on the death 

 certificates as being due to this cause. In accepting these reports we admit 

 that the real cause of 35 per cent of the mortality in Manila of infants 

 under 1 year of age is unknown to us. 



BRONCHITIS. 



Table IX, opposite page 160, shows the results of necropsies on 27 cases 

 in which the death certificate gave acute or chronic bronchitis, or broncho- 

 pneumonia as the cause of death. Some of the bodies were in bad condi- 

 tion when they came to autopsy, owing to warm weather supervening 

 and the difficulty of transferring them to the morgue with sufficient 

 promptness.

INFANTILE BEHIBERI. 



Table X, opposite page 160, gives the results in cases of alleged 

 infantile beriberi. The first cases of so-called infantile beriberi which 

 we investigated in November proved to be of Asiatic cholera, and we 

 were at that time somewhat doubtful of the existence of the former disease 

 in infants and rather expected that our experience with alleged acute 

 meningitis would be repeated. Further study showed that a large number
